Ensure server parameter 'audit_log_events' has 'CONNECTION' set for MySQL Database Server (Manual)

Profile Applicability

• Level 2

Description

Set audit_log_enabled to include CONNECTION on MySQL Servers.

Rationale

Enabling CONNECTION helps MySQL Database to log items such as successful and failed connection attempts to the server. Log data can be used to identify, troubleshoot, and repair configuration errors and suboptimal performance.

Impact

There are further costs incurred for storage of logs. For high traffic databases these logs will be significant. Determine your organization's needs before enabling.
